Anonymised Summary of the Opinion

Factual and Procedural Background

This is an appeal against an order made by Judge Lieven on the application of a local authority (the "Local Authority") seeking the return to England and Wales of a British infant (referred to in the source text as "J") who was born in Thailand and is currently there. The appeal was brought by the child's father with the support of the mother.

Background facts (as summarised by Judge Lieven and reported to this Court):

• The parents have a long history of involvement with children's social care, including findings about poor mental health, alcohol and substance misuse, association with risky individuals, criminality and domestic abuse affecting their ability to keep children safe.
• The mother became pregnant in 2024. When she was mid-pregnancy the parents travelled to Thailand in September 2024 with the stated aim of avoiding removal of the baby at birth. The mother gave birth in Thailand in December 2024.
• The parents returned to England in June 2025 and were arrested; they stated that they had left the baby in Thailand with acquaintances ("Person X" and "Person Y") and later indicated the child had been placed in a childcare facility / orphanage and spent time with others.
• The Local Authority applied to the High Court to invoke the High Court's inherent jurisdiction to make the child a ward of court and to order her return to England, asserting either that she was habitually resident in England or, alternatively, that as a British national the court could exercise the inherent jurisdiction.
• Without notice, an interim order was made making the child a ward of court and imposing a passport order. The substantive hearing before Judge Lieven took place on 7 August 2025; judgment was handed down on 15 August 2025, ordering the child's return to England. The father appealed on two grounds. Permission to appeal was granted and the stay of the return order was extended pending the appeal. This Court dismissed the appeal.
• At the time of the appeal, the child remained in Thailand, primarily in a childcare facility. Thai authorities had indicated a willingness to assist the Local Authority to secure the child's return.

Legal Issues Presented

1. Whether Judge Lieven correctly applied the legal principles governing the High Court's inherent jurisdiction to order the return of a British national child who is outside the United Kingdom (including the requirement that the inherent jurisdiction be exercised only in "sufficiently compelling" circumstances).
2. Whether, on the facts, the circumstances were sufficiently compelling to justify the exercise of the inherent jurisdiction to order the child's return to England (including whether the judge gave appropriate weight to the statutory scheme, international instruments and the protective measures available in the foreign state).

Arguments of the Parties

Appellant's Arguments (the Father)

• The judge failed properly to apply the principles in the authorities (in particular Re M and Re D) by not giving sufficient weight to the prohibition on "cutting across" the statutory jurisdictional scheme reflected in the Family Law Act 1986.
• The judge did not adequately consider the context and purpose of the Local Authority's application, which the appellant said was to secure the child's return so that the Local Authority could start public law (care) proceedings — i.e., that the order was a means to enable public law steps that could not be taken while the child remained abroad.
• The judge treated previous Supreme Court observations as applying to "bare return orders" only and failed to recognise that the case law required a particularly high bar where the Local Authority's aim was effectively to bring the child into the jurisdiction to trigger statutory public law powers.
• The judge erred in concluding that the facts met the high threshold: insufficient weight was placed on Thai reports that the child was doing well and on the effectiveness of child protection arrangements in Thailand; the judge treated speculative factors about the parents' situation in Thailand as determinative.

Respondent's Arguments (the Local Authority)

• The judge correctly and carefully applied the authorities governing the inherent jurisdiction and the high threshold for its exercise, including the requirement that the circumstances be "sufficiently compelling".
• The Local Authority's primary purpose was protective: to secure the protection of a British national child who was effectively abandoned in Thailand with no one exercising parental responsibility and living largely in an institutional setting.
• The fact that the Local Authority intended to issue care proceedings on the child's return did not, of itself, render an application under the inherent jurisdiction improper; the use of the jurisdiction to secure the child's safe return for protection is permissible where the high threshold is met.
• On the facts the judge was entitled to draw adverse inferences from the parents' conduct (including the failure to comply with drug testing orders) and to assess the risk as sufficiently compelling to justify return under the inherent jurisdiction.

Guardian's Position

• The guardian supported the Local Authority's position that the parens patriae jurisdiction can be exercised to order the return of a British child abroad where circumstances are sufficiently compelling, and that such orders are not inherently forbidden by the Family Law Act 1986.
• The guardian submitted that the judge correctly identified and applied the legal principles and was entitled to conclude that the factual threshold was met on the evidence before the court.

Court's Reasoning and Analysis

The Court's analysis proceeds from a careful mapping of the statutory and international jurisdictional framework and the domestic case law concerning the High Court's inherent jurisdiction to protect British children abroad.

Key legal framework points summarised by the Court:

• The Family Law Act 1986 (FLA 1986) contains statutory jurisdictional rules for certain Part I orders, but its scope does not encompass public law care orders under Part IV of the Children Act 1989; therefore, the FLA 1986 has limited direct application to Local Authority public law applications.
• The 1996 Hague Child Protection Convention (the "1996 Convention") governs jurisdiction where it applies (primary basis: habitual residence), but where the Convention does not apply domestic law bases of jurisdiction (including the inherent jurisdiction) may be exercised — albeit that other Contracting States are not bound to recognise such wider domestic bases of jurisdiction.
• The Children Act 1989 imposes duties on Local Authorities and restricts the inherent jurisdiction in specified ways (notably s.100), including that a Local Authority cannot use the inherent jurisdiction to place a child in its care or confer powers of parental responsibility without leave and only if certain conditions are met.
• Historic and modern authorities confirm that the High Court retains an inherent protective jurisdiction (parens patriae) to act for British nationals abroad, but appellate authority emphasises that the jurisdiction should be exercised with great circumspection and only where circumstances are "sufficiently compelling" so as to make protective intervention necessary.

Application of those principles to the facts:

• The Court accepted Judge Lieven's formulation of the applicable test (drawn from Moylan LJ in Re M): although the inherent jurisdiction is not confined only to the most extreme cases, there must be circumstances "sufficiently compelling to require or make it necessary" that the court exercise its protective jurisdiction.
• Judge Lieven considered the relevant authorities (including A v A, Re B, Re M and Re D) and identified three core points to guide application: (a) the inherent jurisdiction exists to make return orders for British children abroad; (b) its exercise requires great caution; and (c) there must be sufficiently compelling circumstances, with attention to protective measures available abroad, factual circumstances of the child, and the relationship with the Family Law Act 1986.
• On the facts, Judge Lieven identified several factors in favour of a return order: the parents' extensive prior history of serious social care concerns; evidence of drug use and criminality; deliberate steps taken by the parents to avoid scrutiny (travelling abroad pregnant, concealing the child's birth, misleading documents); failure to comply with UK court orders for drug testing (and drawing adverse inferences); the child's placement in Thailand with temporary carers and in a childcare facility; and the prospect that the parents would seek to frustrate safeguarding efforts due to prior deceit.
• She also weighed factors against return: reports from Thai authorities that the child appeared well; the child's current day-to-day care seeming adequate; that separation was in part due to UK passport orders; and the existence in principle of Thai protective mechanisms.
• Judge Lieven concluded that, notwithstanding the mitigating matters, the balance of factors showed the statutory high threshold was met: the circumstances were sufficiently compelling and the exercise of the inherent jurisdiction was necessary to protect the child as a British national.
• This Court analysed whether Judge Lieven had misunderstood or misapplied the legal principles relied on by the parents (particularly Re M and Re D) and concluded she had not. The Court rejected the submission that the return order impermissibly "cut across" the statutory scheme merely because the Local Authority planned to issue Part IV care proceedings after return; the Court held that the primary purpose of the application in this case was protective rather than an improper attempt to obtain statutory powers unavailable while the child was abroad.
• The Court also noted an omission in the formal orders: no explicit record that leave under s.100 Children Act 1989 had been granted, although the order contained an express recital that the judge had reasonable cause to believe the child was likely to suffer significant harm if inherent jurisdiction were not exercised — a recital the Court treated as demonstrating the judge's satisfaction for the purposes of leave. No party had argued that leave had been refused.
• On appellate review of Judge Lieven's fact-finding and application of law, the Court applied the well-established principle of appellate restraint: absent an error of principle or a conclusion no judge could reasonably have reached, the appellate court should not interfere. The Court held Judge Lieven's assessment was within the range of reasonable conclusions and that no such error of principle or unreasonable conclusion was demonstrated.

Holding and Implications

DISMISSED

Holding (core ruling): The appeal against Judge Lieven's order for the return of the British child born in Thailand was dismissed. The Court upheld the judge's conclusion that the High Court's inherent jurisdiction could be exercised in the circumstances and that the factual threshold of "sufficiently compelling" circumstances to make a return order had been met on the evidence.

Implications:

• Immediate consequence for the parties: the order for the child's return to England (made by Judge Lieven on 15 August 2025) stands subject to any subsequent procedural steps required by the court order and by any enforcement arrangements with the Thai authorities. The child remained in Thailand at the time of the appeal, and the Court noted the Thai authorities had indicated willingness to assist the Local Authority to arrange the child's return.
• Legal consequence: the Court reaffirmed that the High Court's inherent parens patriae jurisdiction continues to be available to order the return of a British national child abroad where the circumstances are sufficiently compelling to require the court's protective intervention, while emphasising the high threshold and the need for caution. The Court rejected a proposition that a Local Authority may never invoke the inherent jurisdiction where it intends to commence public law proceedings after return; instead, the permissibility depends on the purpose and the factual context.
• Precedential stance: the judgment applies and synthesises existing authorities (including A v A, Re B, Re M and Re D) but does not purport to create a novel legal principle. The Court indicated that some earlier obiter comments (about "cutting across" statutory schemes) have generated uncertainty and may warrant reconsideration in an appropriate future case, but this judgment did not undertake such a reconsideration. In short, no new broad precedent or statutory reinterpretation is announced beyond the application of established principles to the facts before the court.
